Abstract
A fuse element prepared from, for example, polycrystalline silicon is deposited on an insulating layer provided on the main surface of a semiconductor substrate in which an IC memory is formed. Connecting portions are integrally formed at both ends of the melting away portion of the fuse element. Each of the connecting portions has a stepped surface having stepped sections. The stepped surface is tightly contacted with a stepped surface having stepped sections formed on the insulating layer.
